I Morris Danced when I was young, foolish, and white. I was a longhair hippy too. I never dressed as a Native American (except for wearing beads) nor a Polynesian (except that Hawai’ian shirt) nor as an East Indian (except baggy Madras trousers) nor a Brit (except the collapsible black top hat). I never tried yellowface or redface or blackface (except Army camo).
Have I appropriated cultures? Sure. Playing 'oud lets me steal Turkey. I steal Hawai’i when I play 'ukuleles. I steal Africa when I play banjos (one made in Korea). Celtic and Arabic pipes and whistles. German harmonicas (made in China). LatinX stringed axes. And I want a sitar.
To fight cultural appropriation, ban musical instruments. They’re all foreign.
